This is a first-level course, consisting of five blocks, and is intended as a short introduction to calculus. Calculus is increasingly being recognized, and accepted, as a powerful tool in the exact sciences and social sciences. Its power stems from two sources – the derivative and the integral. In this course, we shall acquaint you with the basic techniques of differential and integral calculus. We shall also briefly trace the historical development of calculus.

We shall begin the course with essential preliminary concepts, in the first block. You will be introduced the concepts of ‘limit’, ‘continuity’, and ‘derivative’ in the second and third blocks. We shall discuss the geometrical significance and application of the derivative in the fourth block. The fifth block focuses on the other important concept of calculus, namely, integral.

This course of Differential Equation assumes the knowledge of the course BMTC-131 on Calculus. The studies in this course are divided into four blocks.

Block-1 deals with functions of two and three real variables. The purpose of this block is to provide the basis for studying the remaining blocks of the course. We have given a brief discussion on 3D-cordinate system and discussed the algebraic and geometrical structure of R2 and R3. The notions of limit, continuity and differentiability are extended for functions of 2 and 3 variables. This block also covers chain rule and homogeneous functions.

We have started Block-2 with the essentials and the basic definitions related to the study of differential equations. After discussing various methods of solving first order ordinary differential equations (ODEs) we have formulated some of the problems of physical and engineering interest in terms of first order linear differential equations. In Block-3 we have laid specific stress on the applications of second order ODEs.

In Block-4 we have discussed simultaneous, total and partial differential equations (PDEs). Here we have classified the first order PDEs into linear, semi-linear, quasi-linear and non-linear PDEs and discussed the various types of solutions/integrals of these PDEs.

All the concepts discussed are followed by a lot of examples as well as exercises. These will help you get a better grasp of the techniques discussed in this course.
